Modular DC to DC Converter Part Number: 012-550-20 |  |  | - Remote equipment powering over multiple copper pairs
- 48VDC to +/-137VDC (CSM35)
- Two 100VA circuits per power module
- Up to 2400W per 19in shelf
- Scalable hot plug-in operation
The CSM35 is a compact, modular DC to DC converter system designed for distributed power communications applications, specifically optical network units. Using switched mode technology, the CSM35 provides outstanding efficiency in a compact design.
The CSM35 packs maximum power into minimum space, but doesn’t compromise on features. A fully equipped CSM35 system will include up to 12 modules in a 19in shelf.
Alpha’ CSM 3x modular DC to DC converter systems incorporate a full range of standard and optional features, including current/power limiting and individual ground fault interrupt options for each circuit. |  |
